Daily, if the corpora are sufficient for masscheck scoring to run.
At the moment the masscheck corpus is ham-starved. There's not quite
enough ham available for reliable scores to be generated and published.
Once again, participation as a mass-checker, especially if you can provide
a non-English ham corpus, is solicited. If you have access to thousands of
reliably-categorized messages and can set up a box to run SpamAssassin to
scan them to test the performance of the base rules, please consider
becoming a masscheck contributor. The content of private messages is not
exposed by this process, only the rule hits are public.
If you can do this, see the wiki for the process and contact Kevin McGrail
for upload credentials. Thanks!
I've been idly debating figuring out how to contribute, but having read the
wiki articles, I have a few questions:
Is older ham useful? It specifically mentions that older spam isn't useful,
and why, but I'm thinking older ham is probably useful since old mail clients
and legitimately sent mail never dies. But I could filter based on date.
There's some debate about that. :)
I personally agree with you. Others disagree.
Is mail "Sent" folder mail of any use? I suspect not, since there's not
necessarily a Received header yet (although there might be, it depends on how
the user sent the message), so direct-to-MX and similar rules will skew.
Is a ham-only corpus submission useful? Our ham is well cleaned, but we don't
archive spam on an ongoing basis, and users primarily just delete spam. But
most of our users archive ham and retain it, so depending on what the results
look like, it might be useful data source.
Yes, ham-only masscheck submissions would be very welcome.

Men by their constitutions are naturally divided in to two parties:
1. Those who fear and distrust the people and wish to draw all
powers from them into the hands of the higher classes. 2. Those who
identify themselves with the people, have confidence in them,
cherish and consider them as the most honest and safe, although not
the most wise, depository of the public interests.
